Example Handshake Traces for TLS 1.3
draft-ietf-tls-tls13-vectors-07

Abstract

Examples of TLS 1.3 handshakes are shown. Private keys and inputs are provided so that these handshakes might be reproduced. Intermediate values, including secrets, traffic keys and IVs are shown so that implementations might be checked incrementally against these values.

Table of Contents

1. Introduction

TLS 1.3 [TLS13] defines a new key schedule and a number of new cryptographic operations. This document includes sample handshakes that show all intermediate values. This allows an implementation to be verified incrementally, examining inputs and outputs of each cryptographic computation independently.

A private key is included with the traces so that implementations can be checked by importing these values and verifying that the same outputs are produced.

Note:
Invocations of HMAC-based Extract-and-Expand Key Derivation Function (HKDF) [RFC5869] are not labelled, but can be identified through the use of the labels used by HKDF.

2. Private Keys

Ephemeral private keys are shown as they are generated in the traces.

The server in most examples uses an RSA certificate with a private key of:

3. Simple 1-RTT Handshake

In this example, the simplest possible handshake is completed. The server is authenticated, but the client remains anonymous. After connecting, a few application data octets are exchanged. The server sends a session ticket that permits the use of 0-RTT data in any resumed session.

4. Resumed 0-RTT Handshake

This handshake resumes from the handshake in Section 3. Since the server provided a session ticket that permitted 0-RTT, and the client is configured for 0-RTT, the client is able to send 0-RTT data.

5. HelloRetryRequest

In this example, the client initiates a handshake with an X25519 [RFC7748] share. The server however prefers P-256 [FIPS186] and sends a HelloRetryRequest that requires the client to generate a key share on the P-256 curve.

Note:
The HelloRetryRequest uses the same handshake message type as a ServerHello and so is labeled as ServerHello here.

6. Client Authentication

In this example, the server requests client authentication. The client uses a certificate with an RSA key, the server uses an ECDSA certificate with a P-256 key. Note that private keys for the certificates used this example are not shown.
